    User Reviews about Garmin GPSMAP 431S GPS Dual Beam Combo

    The unit has a nice clear screen that shows up well in any light conditions. I have the same problem with this unit that I had with my handheld Garmin. The Inland Lakes software does not properly show the location of the boat. It will display the boat skidding along on dry land when you are 200ft. off shore. This seems to be a problem with the way the software interacts with the unit. If you save the track to a computer, open Inland Lakes there, it will always show the boat in the water. Trying to explain this to Garmin support is like talking to my cat. I have had a lot of Garmin products and they work well for the most part, but, support is almost nonexistent. -- Unit looks good
